Scope

Main Technical Content: 3 **Environment and Facility Conditions** 3.1 **Site Selection for Farms** The environmental conditions of the farm site should meet the requirements of GB/T 18407.4. Generally, the site is selected in areas with sufficient water sources, no pollution sources, good water quality, convenient transportation, and access to electricity and water. 3.2 **Pond Conditions Requirements** Ponds should be easy to drain and manage, with minimal silt on the bottom, loamy soil, and solid, leak-proof embankments. The water intake system typically consists of sand filtration wells or storage tanks, pumps, and water intake channels, which are kept separate and equipped with necessary farming equipment or facilities according to intensive farming management requirements. The pond area and water depth are shown in Table 1. **Table 1: Suitable Pond Areas and Water Depths for Bamboo Shell Fish** Pond Type Pond Area (m2) Water Depth (m) Seedling Ponds 667–2000 1–1.5 Finishing Ponds 2000–6670 1.5–3.5 Mixed Ponds >2300 1.5–3.5 3.3 **Water for Farming** The water used for farming must undergo purification treatments such as sand filtration and disinfection, and meet the requirements of GB 11607. 3.4 **Aeration Equipment** Aeration machines can be selected from waterwheel-type aerators, propeller jet aerators, or bottom-inflated aerators. For every 2 m of water depth, a 0.75–1 kW aeration machine is installed per 667 m2 of pond. The aeration machines should be properly installed and operated, with attention to electrical safety. In areas without power supply, generator sets or diesel-powered aeration equipment should be used. 3.5 **Analysis and Testing Instruments** Biological microscopes, water temperature gauges, dissolved oxygen meters or dissolved oxygen analysis kits, pH value analysis kits, and ammonia nitrogen and nitrite analysis kits should be provided. 4. **Preparation Work Before Stocking** 4.1 **Pond Prep
